The frame of the machine comprises a table a supported upon legs andrigidly supporting standards a a which are provided at a, crgwith fixedbearings for a horizontal i shaft Q.

Mounted upon this power driven shaft are a number of cams-andeccentrics,

- for purposes hereinafter described.

Fixedupon the table a is a blanking die 65 elevated from said table byend supports (Z 65?, so that a raising die, to be hereinafter described,can be positioned below said Ametal stripe, from which the blank isshaft 0, as clearly shown by Fig 2, and by devices, also shown in Fig. 2now to be described. r v I e? s aslide novable on the table, a, at-

The slide f is moved downwardlyby a cam f onthe shaft 0 and upwardly by a spring F, the slide being suitably guidedin a part a? of the frame, and carries a roller) making contact with thecam f while the spring f is preferably of the coiled type extendingbetween the The slide 6 is operto the frame at g? and operated'by a camg andby a s pring'g a roller 9 on the lever contacting the cam g and alink 9. pivot-.

ally connecting the one end of thelever to the slide 6 The feedingvofthe strip 6 is intermittent and timed to the other parts of L themachine, as will be hereinafter explained.

WVorking above the blanking die d is a 4 blanking punch it carried by aslide 7L guided in the'frame part a and positively moved up and down byan eccentricstrap 715 working on'an eccentric h carried b the shaft o,the rod of the eccentricstrap L3- being con:

7 nected with the slide at if, The cutting edge 'h jof this blankingpunch cooperates with the blanking die to cut a blank from the strip 6.

i Associated with the blanking punch 72. is an; inner pressure plate 72];(Figs.' 3 and i) having a vertical stem it 'slidably guided in thepunch h. The upper end of the stem is adapted to contact an, abutment h"ad- 'justably carried uponthe lower end of a slide 7L guided vertically'in the frame part w and moved "downwardly by a cam f h on the shaft 0andupwardly by a spring it. An extensible coiled spring It normallyholdsthe stem k against the adjustable represented by Figs. 3 and 1-.

abutment h. The pressure plate k moves downwardly with the punch it,being carried by it, but additionally moves downwardly, independent ofthe punch, after the blank has been cut by the punch, as will behereinafter explained. The slide it moves independently of the slide 72but relative thereto, so that the pressure plate if only operates at acertain moment and for a certain period, as will be also hereinafterexplained.v The lower end of the slide h projects through a free slot inthe slide it from the back, and the abutment h" is adjustable on saidlower end for convenience in setting the stem to the slide.

Mounted upon the table a, is a slidable carrier 6 fora raising die j,and itsassociated parts, and for a stripper device 1 the latter to behereinafterdescribed. The die j is xed to the carrier 2', and thecarrier works in V grooves of thetable, asshown in Fig. 2. The movementof the slidable carrier i is beneath a raising bar hereinafterdescribed,

and the other beneath the blanking die (Z as,

Said slidable carrier is actuated by a cam Lion the main shaft through alever 70 fulcrunied to the standard a at 74 and coupled to the slide bythe pivoted link 10*, the timing of movement bringing the raising dieunderneath the blanking die cl to receive a cut out blank 2 andafterwards carry the blankaway for further operation. The raising die jpro-' vides a shaping cavity j and above this cavity a set edge j forpositioning the blank zabove the cavity, clearly shown by Figs. 5

and 9. Four" vertical pegs pass through this raising die from below,clear of the'shaping cavity, and are moved up and down as one piece witha stem 3' working in the carrier slide 71 and connected at with aslotted arm 7' rigidly carried upon the lower end of an extension j ofthe vertical slide f,

Disposed above the raising'die is araising bar Z, and above the risingbar an upper punch m, both to co-operate with the raising die 7' toraise a blank into il-shape and afterwards closeits sides to form anopen tube surrounding the raising bar Z, to be subsequently strippedfrom said bar, The raising bar -Z horizontally disposed to the shapingcavity 7' of the die j, and'is rigidly carried at its one end by-aplunger Z moved i reaaeia thwmrardly bysai e Zt on: th sh fte nd.upwardlyby a spring the, plunger carrying a roller J which, contactswith the, cam .Z and;.,be ing .guidecl .;in its movement inthe Theoperation of the raisingnbar'ilhpongthe blank .Within the raising the jis .clearly represented-by-Figs. ,6 and 7,.andsince-said raising bar hasa free send 1 to enableithe"articleto be stripped,
